GMRS/FRS Frequencies
FRS & GMRS Frequencies
Basic frequencies and max power for licensed GMRS operators. Some FRS and GMRS frequency overlap. To further complicate things, the FCC's labeling has changed. See Buy Two Way Radios - Chart for more information.
GMRS Repeaters
Typical GMRS repeater settings.
Approximate FM Radio Range
This is my collection of various stats and what I've experienced on how far a "typical" store purchased FM "walkie-talkie" transceiver will radiate. Of course, this is a general guide... a thousand things can change in the real world.
